Model # 50UX57B, Chassis # AP83R, dead, was worked on elsewhere, both convergence IC's were replaced, & E995, E996, as well as IK04, & IK05. D910, & D9110 12 volt zener diodes shorted, C707 near the flyback, & horizontal output are fine, the SMPS just won't oscillate! The three opto couplers check ok, as well as the SMPS electrolytics! Ideas anyone? Thanks, Dani.
